RNAi against spn-2 partially suppressed the ray 1 phenotype in plx-1 mutants. Ray 1 is frequently displaced anteriorly, sometimes outside the fan, in plx-1 mutants.
RNAi against gcn-1 in plx-1 mutants suppressed the ray 1 phenotype of plx-1. Ray 1 is frequently displaced anteriorly, sometimes outside the fan, in plx-1 mutants.
IFB-2 localizes in a continuous apical band in wild type. In younger par-6(M/Z) embryos, IFB-2 is apical but not always continuous between cells. Apical IFB-2 patches separate and circularize in older par-6(M/Z) embryos.
In wild type, HMR-1 and DLG-1 are present together in apical junctions within adjacent domains. In par-6(M/Z) embryos, HMR-1 and HMP-1 are apical but fragmented and do not colocalize.
